What Size Box Fits in a Padded Flat Rate Envelope?

When it comes to shipping packages, one of the most convenient options is the USPS's Flat Rate service. With this system, you can send your package without worrying about calculating the exact weight and dimensions, as the cost is fixed regardless of the item's size or weight. However, before you start packing your package in a Flat Rate envelope or box, it's essential to know what size box fits inside the padded flat rate envelope.

To qualify for Flat Rate pricing, the container must meet specific requirements. According to the USPS guidelines, the design of the container should not be enlarged by opening the sides, and the container should not be reconstructed in any way. The flaps and seams can be reinforced with tape as long as they are applied within the normal folds.

There are several sizes available for Flat Rate Envelopes and Boxes, each with its own set of measurements. For instance, the 2-1/2' x 9-1/2' Legal Flat Rate Envelope is suitable for documents and legal papers, while the 2-1/4' x 12-1/4' x 6' Large Flat Rate Box can accommodate larger items.

When it comes to padded flat rate envelopes, the size that fits inside will depend on the specific envelope you are using. The USPS offers several sizes of padded flat rate envelopes, including a 2-1/2' x 9-1/2' Gift Card Flat Rate Envelope and an 11/16' x 5-7/16' x 1-3/4' Outside Medium Flat Rate Box.

In summary, the size box that fits in a padded flat rate envelope will depend on the specific envelope you are using. Before choosing your packaging material, make sure to check the USPS guidelines and ensure that your container meets the necessary requirements for Flat Rate pricing.
